The match in Melbourne showcased Sabalenka's resilience in a tight second set. Mboko, the 2025 WTA Newcomer of the Year, mounted a strong comeback but fell short in the tiebreak.
Aryna Sabalenka began her match against Victoria Mboko with commanding play, securing the first set 6-1 in just over 45 minutes. Playing on Rod Laver Arena for the first time, Mboko faced a formidable opponent in the World No. 1, who extended her lead to 4-1 in the second set. However, as in her prior victories over Bai Zhuoxuan and Anastasia Potapova, Sabalenka's intensity waned with the advantage.
Mboko capitalized, breaking Sabalenka's serve twice in the second set. At 5-4, Sabalenka reached match point but failed to convert three opportunities, allowing Mboko to force a tiebreak. The Canadian pulled the 12th game to deuce, coming within two points of a deciding third set. Yet Sabalenka, a two-time Grand Slam champion, thrived under pressure, dominating the tiebreak 7-1 to win in 1 hour and 26 minutes.
This victory extends Sabalenka's unbeaten streak in Grand Slam tiebreak sets to 20. Mboko, recognized as the 2025 WTA Newcomer of the Year, showed promise against the top seed but could not overcome the late surge. Sabalenka's path to the quarterfinals highlights her ability to elevate her game when it matters most at the Australian Open.
